they surrounded me like a pack of wolves. and they said, go get those crime scene photos of her mama and daddy. i was trying to cover my face.

and he was pulling my hands off of my face. and he said, you did this. you. and i said, i did not. >> a sprawling southern family with a pair of church-going grandparents at its heart. >> they were definitely the most loving individuals i've ever met in my life. >> there was no way it was supposed to end like this. >> she took me by the hand and said, sugar and charlie have been murdered. >> the former church deacon and his wife. who on earth would want them dead? >> it doesn't make sense. they were loved by everyone. >> everyone, maybe, but their own daughter, who admitted to a bitter, simmering dispute. >> has been a long life family feud. >> bambi needed her stepfather and mother dead so she could get her property back. >> evidence pointed to her boyfriend as an accomplice. >> you got the victim's blood on your shoe. he was there. >> or was he? >> no ir

dna? >> nothing. >> a once-loving family now gripped by suspicion. >> i had a lot of people in my ear saying that she did it. >> would the terrible truth rip them apart? >> this cannot be happening. >> i'm lester holt, and this is "dateline." here's dennis murphy with "the deed." >> reporter: the old barn is a shambles now. the fields back in the day so lush and productive gone to seed. the farmhouse empty. time was, the farmland in horry county was some of south carolina's finest. bambi bennett's granddad owned a big spread and created a legacy for the generations to come. >> that barn used to be a tobacco barn.

property? >> uh-huh. he did farming and tobacco. >> reporter: bambi's roots here are as deep as the old oak tree draped in spanish moss that still stands tall in the front yard. they say land is worth dying for because it's the only thing that lasts, and truer words might never have been spoken. in this case, a beautiful piece of land turned out to be nothing but trouble. this is where bambi bennett's family was ripped apart by an act of cruel, unspeakable violence. bambi, her given name, was a fun, feisty good old girl, country through and through. >> i was at my grandparents' a lot growing up. we gardened, and we had a big yard. you know, a huge yard. >> reporter: you're a country girl. >> uh-huh. >> reporter: but

her share of heartache even at a tender age. her parents divorced when she was just 6. mom remarried. then a few years later came that terrible day she will never forget. >> my daddy and my granddaddy passed away on the same day. i was 12 years old. >> reporter: so all of a sudden you'd lost the two important men in your life? >> uh-huh. >> reporter: it was a bewildering and tragic day. there was so much sudden loss to absorb, that young bambi, not yet a teenager, paid no mind to her grandfather's and father's wills. but it turned out she'd been left the entire homestead, all 240 acres of it, to be held in trust until she turned 18. not long after bambi inherited the farm, her stepfather charlie moved the family onto the property, her property. most everybody called him big charlie. bambi called him daddy. >> daddy loved hunting and fishing, and we always had fish

there was always people down at the barn. >> reporter: you call your stepfather "daddy." >> uh-huh. >> reporter: easily do that, huh? >> uh-huh. i've always called him daddy. >> reporter: big charlie was a deacon at church. and he started a small business selling and installing glass, converting the old tobacco barn into his shop. bambi's mom diane worked as a secretary in the public schools. they were a respected, happy couple, salt of the earth. >> she was the backbone of that family. >> reporter: bambi's cousins jessica and amy loved their aunt diane. >> if your car literally stopped in front of their house or broke down, she would go and make sure you had a meal or you were warm. and while she was doing that, big charlie would be like fixing the car. >> reporter: good mom? >> fabulous mom. >> outstanding. >> i mean, her biggest thing was she wanted to make sure her kids were protected and their hearts were protected. >> reporter: and her daughter bambi would need a lot of protecting.

rush. married to her high school sweetheart and divorced after a few months. by the time she was just 24 years old, she had another failed marriage and was struggling as a single mom trying to raise two boys, cody and nathan. that had to be tough, keeping your household going, huh? >> yes. >> reporter: and things went from bad to worse. bambi started popping painkillers. the old story, huh? >> yes. >> reporter: just gobbled them down when you could get them, huh? >> i liked the way it made me feel. >> reporter: bambi was a single mom hooked on pills and sitting on a piece of land worth a small fortune. diane decided it was time to intervene before, say, another whirlwind husband du jour got half of the property. >> mama said, if you put it in my name, it will be protected. >> reporter: and so she signed the deed to her property over to her mom. and then bambi signed over her heart, sending cody and nathan to be raised by their

she calls it her lowest point. >> i didn't want to do it, but i knew it was the right thing. she wanted to take care of them. she loved those children. >> reporter: it was a crushing loss, no question, but bambi agreed at the time the boys were better off. they loved diane and charlie. >> they're just very loving. like, did a lot of outdoor stuff. i mean, they spoiled us to death. >> reporter: nathan, how about you? . they were the most loving individuals i've ever met in my life. my grandma's the most sweet woman, and everybody says so. >> reporter: with the boys living at their grandparents, bambi tried to get her own life back on track. that's when she met rick gagnon, a new hire at charlie's glass company. there was an instant attraction. >> i've always liked the bad boy image, you know, i guess. like, he had the goatee and the shaved head. i don't know. we just had a good time together. >> reporter: was it a serious relationship? >> yes. it was. >> reporter: r

he confronted bambi about her demons. >> i told her, if she wanted to be in a relationship, she had to do something about the pills. >> reporter: by the spring of 2005, bambi felt she had turned the corner. she and rick found a home of their own in myrtle beach. after a long struggle, she was ready to be a mom to her boys again. >> i was getting on my feet. and i just -- i wanted cody and nate there with us. >> reporter: grandparents charlie and diane agreed, very reluctantly, to let the boys move in with bambi and rick. but no sooner had the boys moved then diane was making the case to get them back. >> mama was concerned. >> reporter: did she want to hold on to the boys? >> she said that she would like for them to, you know, continue to stay with her. >> reporter: boyfriend rick thought bambi couldn't catch a break with her family. >> everybody pretty much treated bambi like crap. it stemmed from, you know, issues that diane, charlie and bambi had.

simmering into an angry family drama. then just a few weeks after the boys were turned the over, it happened. it was april 12th, a tuesday morning. bambi called her mom. no answer. big charlie was late for work. one of his barn employees went up to the house to look for him. moments later, he called 911. >> 911. >> she's laying on the floor. and there's blood everywhere. >> there's blood everywhere? >> yes, ma'am. >> oh, my god. >> reporter: inside, things were chaotic. an appalling sight. big charlie and diane were dead. and the old farmhouse they loved so well was now a crime scene. >> charlie and diane parker lying dead in their own home. when we come back, the investigation begins. at a grisly crime scene, some small stray drops of blood might just provide a huge clue. >> it appeared that someone involved in the crime was a bleeder.

>> hello? >> the horror discovered inside that farmhouse confused both the caller and the 911 operator.

she was found lying next to her bed, big charlie sprawled on the bathroom floor. each had been shot multiple types, both by then dead for hours. horry county sheriff phillip thompson's cell phone erupted with calls about the shooting, and he rushed to the scene. not to investigate. charlie and diane were his best friends. >> they weren't just mine. they were everybody's friends. what we remember is how good they were, how kind they were, and what good people they were. >> reporter: down at her house in myrtle beach about 30 minutes from the crime scene, bambi was getting ready to go antiquing with her mom. she called her cell. one of charlie's glass company workers answered. >> i said, can i speak to my mama, please? and he said, bambi your mama and daddy's dead. >> reporter: just like that. >> yes. and i said, what? he said, bambi, somebody's broke in here and killedm.

shot them. and i just dropped the phone and started crying. >> reporter: when bambi arrived at the house, yellow caution tape blocked her way. police were everywhere. >> my mom was like freaking out. >> reporter: rick tried to comfort bambi. young cody turned to him, too. >> and then i remember rick, he was near me, and i was crying on his shoulder. and everybody was just kind of -- it was a madhouse out there. >> reporter: in those moments, it seemed the whole county had gone mad. the murders of diane and charlie came hard on the heels of two other vicious killings nearby. the suspect, a man all over the news named stephen stanko was still at large. >> they were looking for stephen stanko when charlie and diane parker were discovered. >> reporter: vivian skipper was charlie and diane's neighbor. she runs a flower shop nearby.

vivian. is this a kind of thing you could feel in the air or what? >> you could feel it in the air. i was at the flower shop. >> reporter: probably not too thrilled with the idea of getting in your car and driving away. >> i didn't even want to go home. it was pretty bad in horry county that day. >> when i first arrive, what i'm looking at is an opportunity to get oriented to the crime scene. >> reporter: the man responsible for making sense of the crime scene was prosecutor fran humphries, then deputy chief solicitor for horry county. had the house been tossed, rifled? >> it had. one of the first things you do is you look for things -- this appeared to be a home invasion burglary. >> reporter: first take on it? >> first take. no question. >> reporter: it was a gruesome crime scene. the bathroom awash in charlie's blood. there was blood spatter in the bedroom where diane lay. but several feet from diane, there are notably a few small droplets. >> it appeared that someone involved in the crime, not the victims, was a bleeder. >> reporter: why couldn't that be from one of your two victims? >> it was apparent that big che

and it was apparent that diane died where she lay. >> reporter: so it looks like your shooter, your intruder is bleeding. >> is bleeding. >> reporter: so that's great evidence. >> it is if you can match it up. >> reporter: while crime scene techs processed the house, investigators started taking statements. big charlie and diane had a large family and knew a lot of people. >> we talked with everybody. the list of people that we talked to is exhaustive. >> reporter: a parade of friends, employees and family was wrought down to headquarters for interview, including bambi and her boyfriend rick. >> they did gunshot residue tests on all of us. >> reporter: including you? >> uh-huh. >> they had me remove my shirt, lift my pant legs up. they took my shoes, took pictures of my shoes, tops, bottoms. >> reporter: both bambi and rick told police they'd spent the night at home. never left. with the interviews complete, police drove rick and bambi back to the farmhouse. everyone was g

bambi says she realized she'd left her purse with her phone and car keys in the detective's cruiser. she decided she'd take her mother's vehicle to get home. >> we didn't have any way to get in touch with nobody. we didn't have anything. and i told rick, i said, see if you can find mama's purse or cell phone. and so he went in the house. >> reporter: police had released the crime scene, but it still looked like one. detectives told the family they would have to clean it up. so when rick says he went in to fetch diane's car keys, he found himself tip-toeing through a bloody mess. what were you seeing? >> all the blood and just one of the most horrible things i'd ever seen. >> reporter: rick approached the bathroom where charlie had been killed. he says he noticed bambi through the window, pacing in the backyard. >> she was calling out, you know, mama, mama. she was crying, screaming. and i stepped into the bathroom. tried to step around the mess as best as i could. and i shut the blind. >> reporter: and you closed them

>> that's right. i remember saying to bambi, i think i stepped in some blood in the bathroom. and i was, you know, wiping my shoe off on the sand. and she was telling me to wash my shoe so i didn't get blood in her mom's truck. >> reporter: man, that must have been eerie being in that house that night, huh? >> yeah. extremely. >> reporter: it was an eerie moment. one that would haunt bambi and rick for years to come. coming up -- bambi makes a stunning admission. >> it's been a long like family feud.

the cold-blooded killing of big charlie and diane parker had a great many people in and around conway, south carolina, bolting their doors and locking their windows. had you had any trouble in that neighborhood, out in countryside with break-ins? >> not that i know of. i mean, it's always been a

it just doesn't make any sense. >> reporter: was this more of the murderous rampage of the notorious stephen stanko who was all over the news? no, said prosecutor fran humphries, who knew stanko had been sighted in georgia at the time of the murders, 200 miles away. so this awful thing at the farm house, you weren't associating that with stanko? >> i was not. >> reporter: even in the public mind, they might have made that connection. >> oh, they did. but truly at that time law enforcement knew that he was physically in augusta. >> reporter: rather, humphries focused on the evidence coming from the parker crime scene. he quickly came to believe this was more than just a bungled home invasion. >> it was apparent that nothing had been taken. or at least nothing that you would suspect to be taken in a burglary. >> reporter: humphries thought back to some curious statements bambi had made in her interview with police, which she said she had given willingly. >> okay. all right. you sure you're okay to sit down and do t

>> i'm not okay. but i want to help you. >> reporter: soon after the interview started, bambi, he said, began describing in detail a feud within her family. at issue was the land bambi owned and that her parents were living on. >> there has been like a long life family feud. >> right. for a long time. >> reporter: over the land? >> yeah. a long time. >> reporter: according to humphries, bambi and diane argued over who should control that property. >> diane wanted to make sure that that property was there for the kids. i think she had become convinced that, you know, bambi was not going to be in a position to manage that property. >> reporter: i love this girl, my daughter, but she's beyond hope. is that the kind of feeling? >> well, she just can't be trusted with it. >> reporter: bambi didn't agree. >> she wanted the property back. >> i had a lot of anger about that. >> reporter: but humphries learned the land wasn't the only hot button between bambi and her mother and step-dad.

over the raising of bambi's boys, nathan and cody. >> was there any issues where they didn't -- where your parents didn't want the kids to go back to you guys or anything like that? >> well, yeah. i understand my mom had cared for them and all and that was hard for her to give them back. at first we were angry, you know, at each other and being ugly to each other. >> diane just wasn't comfortable with bambi having custody of those children. >> reporter: in fact, just four months before the murders, a mother-daughter shouting match over the care for the boys got so out of hand that diane called 911. the responding officer arrived with his dash cam rolling just moments after bambi had stormed away. >> i'm sorry to bother you. >> no. you're not bothering me at all. >> reporter: diane explained the argument to the officer. >> she usually does what she wants to do. picks them up when she wants to. she doesn't provide anything for them. >> reporter: diane went on to say she felt threatened by her daughter. >> she scares me.

she got in my face and jerked the phone out of my hands when i was calling. >> reporter: and then came this chilling pronouncement. >> it's just -- but if anything happens to me, you'll know that she's the responsible person. >> reporter: how telling is that? she was in fear, in grave fear. >> reporter: humphries by now suspected bambi was somehow involved in her parents' murders. but he was skeptical she could commit a double homicide on her own. so the prosecutor turned his attention to bambi's boyfriend, rick gagnon. >> he was aligned with bambi. he was extremely faithful to bambi. >> reporter: and according to humphries, willing to do anything for her. you got the daughter and the boyfriend who seem to be in some sort of conspiracy, the theory goes? >> well, an agreement to accomplish a goal. >> reporter: the alibi bambi and rick gave detectives that they were at home during the hours leading up to the murders was difficult to prove. each gave the other as a witness. >> she said, we were at home. you know, rick was there. i was there. my boys were in the other room.

>> reporter: the prosecutor began to wonder, could those mysterious blood droplets at the crime scene be linked to rick and bambi? >> the dna results had not come back. we didn't know whose blood that was. >> reporter: you didn't know whose it was, but you knew somebody else was in the house? >> we didn't know. it could have been richard gagnon. >> reporter: while humphries waited for those results, he obtained a search warrant and took another look at some of rick and bambi's belongings, including their shoes. >> there is blood on his shoe. >> reporter: what did the lab analysis say about that? >> it was big charlie's blood. >> reporter: the prosecutor didn't buy rick's story about having stepped in blood while looking for bambi's mother's car keys. detectives also found what they thought was blood on one of bambi's boots. so now you have two persons of interest, fair to say? >> oh, no question. >> reporter: ten days after the murders, humphries asked both rick and bambi to take polygraph tests. both agreed and both showed deception. >> rick gagnon in particular showed deception. >> reporter: police then sat both rick and bambi down in

of questioning. this time the gloves were off. >> do you want to be charged with something? >> are you charging me with anything? >> answer my question. >> i didn't do anything. >> reporter: they hoped for a confession or at the very least, that she'd give up rick. she didn't do either. >> you don't want to be charged? >> no. i'm not going to be charged because i didn't -- >> lock her ass up. >> -- anything. >> we done. lock her ass up. because you're not going to tell us anything. put some handcuffs on her. take her to jail. charge her with two counts of murder. >> reporter: but the detectives weren't done yet trying to break bambi. on her way to her booking, bambi said the hammer came down hard one more time. >> they surrounded me like a pack of wolves. they said, go get those crime scene photos of her mama and daddy. and i said, no, no, no. and i was trying to cover my face, and he was pulling my hands off of my face. and he said, you did this. you.

>> reporter: detectives said the same thing to rick gagnon. >> they arrested me. and that's pretty much it. if bambi did it, then i had to be a part of it. >> reporter: so there it was, a daughter and her boyfriend, partners in love and suspected of murder. the alleged motive was basic. get the deed to the land and resolve the custody issue of the boys in one bloody rampage. horry county could sleep easier at night with case closed. but was it case solved? coming up -- a new family feud breaks out between bambi and her sons. >> i had a lot of people in my ear saying that she did it. i resented her. i hated her. it's time to rethink what's possible. rethink the experience. rethink your allergy pills. flonase sensimist allergy relief

bambi bennett sat in a horry county jail cell stunned. she had just been charged with two counts of murder. >> i thought, i'm just having a bad dream. this cannot be happening. not only were my parents just murdered. now i'm being accused of being the one that killed them. i said, you all have lost your mind. i said, this doesn't make any sense. i didn't do anything wrong. >> reporter: but to prosecutor fran humphries, it made perfect sense. >> the motive is unavoidable in this case. bambi needed her stepfather and mother dead so she could get her property back. >> reporter: property valued at north of a million dollars. the classic question that people in your line of work pose is, well, who benefited? >> bambi. >> reporter: as for bambi's boyfriend rick, humphries believed bambi persuaded him to help her carry out the murderous deed.

you see it? he's carrying out her orders? >> i think he's been her puppet from the beginning. >> reporter: what did you think? >> i don't know. i was scared to death. >> reporter: in cahoots with your girlfriend, bambi. that's the theory, right? >> yeah. i guess so. >> reporter: but both rick and bambi said the prosecutor had it all wrong. they insisted they would never do anything to harm diane or charlie. bambi downplayed the family drama over the land despite calling it a feud during her interrogation. >> she wants the land. that is the most ludicrous thing ever. it was given to me by my daddy to begin with. and even though it was in mama's name, if i wanted the land back all i had to do was tell mama that. >> reporter: also absurd, she said, was the allegation she'd kill her parents over disagreements about how to raise her boys. >> who does not have disagreements ever with their mother or their father? me and mama didn't always agree on the upbringing of cody and nate. but at

that is ridiculous. >> reporter: but by now, even some of bambi's family believed she was responsible for her parents' murders, including bambi's own sons, nathan and cody. you lost your grandparents in the most awful fashion. and then your mom is swept away from your life within minutes. >> it's just crazy. like, you don't know who to turn to. >> reporter: when did you come to the idea that maybe she was the one that did this? >> it was a mixture of thing. like i had a lot of people in my ear saying that she did it. what i came to the conclusion was that she basically like put it in rick's head for rick to do it. >> i only thought she had something to do with it from what i had been told. >> i resented her. i hated her. i didn't want to see her face ever again. >> reporter: it seemed bambi's supporters were few and far between. but one who did believe in her innocence was her attorney jim irvin. >> everybody rushed to judgment in this case. >> reporter: the way jim irvin saw it, the prosecution's case agt

circumstantial one that hinged on a bunch of theories as to motive. >> what always bothered me about this case, when you look at the gunpowder residue, there was none on bambi. >> reporter: he said that one bit of hard evidence detectives thought they had against bambi, what they thought was blood on her boot, turned out to be nothing. >> the detective said, we got her. the dna on this boot's going to belong to one of the two people. they couldn't even say it was dna. >> reporter: as for the polygraph test detectives said bambi failed to pass, according to irvin, those results were suspicious. >> the last question they asked her, have you told me everything you know about this case? if i asked a detective that same question, he couldn't pass it either. it's just too broad a question. >> reporter: bambi sat in jail for six months. they were hoping she'd flip and tell them the story. >> that's exactly what they were hoping. >> reporter: finally the judge said enough is enough. prosecutor humphries had to let bago

>> it became apparent the evidence was not sufficient to bring her case to trial. >> reporter: didn't have the goods? >> just wasn't there. wasn't there. >> reporter: and yet she's the foundation of your theory? >> there's no question about it. >> reporter: for the time being bambi was able to put horry county jail in her rearview mirror and with it rick. by now, bambi had cut ties with her old boyfriend. sounds likes she had your back, rick, and then she didn't? >> yeah. >> reporter: what had happened? >> jail changed people, you know. >> reporter: rick was hoping it would just be a matter of time before he too would be released. the forensics they had against you. there was no hair, there was no fingerprint, there was no dna? >> nothing. >> reporter: but he did have charlie's blood on his shoe. to humphries, that evidence was part of a bloody trail from the crime scene that was about to lead both the prosecutor and rick gagnon into a courtroom showdown. coming up -- one of rick gagnon's

he shared his woes with another guy in a jumpsuit, two inmates power walking together around the yard. >> we would walk around the pod, do laps. >> reporter: the jailyard buddy was named robert mullins, a petty crook who seemed strangely interested in rick's troubles. did he want to talk to you about the case? was he grilling you? >> yeah, all the time. all the time. >> reporter: but then it seemed everyone in this part of south carolina wanted to know more about the case and its two beloved victims. it took three years, but in 2008 the state was ready to try rick gagnon for the murders of charlie and diane parker. a camera was rolling as prosecutor fran humphries began his case. >> so this is purely motive evidence which establishes a motive for richard gagnon to end the lives of these two people. >> reporter: as humphries recalls, the case against rick was always motivation strong, evidence weak. not much more than a drop of

charlie parker's blood on a shoe when you came right down to it. even so, humphries told the court the blood put rick at the murder scene. but he had a story for it, didn't he? >> he did. it didn't hold water, but he had a story about it. >> reporter: humphries recited rick's version of how blood got on his shoe. how he'd gone into the parker house to get a set of car keys some time after crime scene techs had finished up. >> he looked to his right, which was the window leading in to the bathroom where big charlie had died and noticed the blood. >> reporter: rick said he worried bambi, pacing outside, might look in the window and freak out all over again. >> he went in and stepped through the bathroom and closed the blind. >> reporter: and whoops, i stepped in the blood. that's his story though, right? >> yeah. >> reporter: but it didn't hold up? >> no. because it was already closed. >> reporter: that was the gotcha. this crime scene photo, said the prosecutor, was taken hours

inside that house. notice the bathroom blinds are drawn. humphries argued that rick could not have closed the blinds because they were already shut. the prosecutor said the defendant was lying, though he believed rick had told the truth about the murders to at least one other person, the state's star witness, robert mullins. the witness i call the jailhouse snitch and you probably call a jailhouse informant. >> oh, he's a snitch. no question about that. at the end of the day, what we learned from robert mullins is that he's been given a fairly detailed account by gagnon of what occurred that evening and what the crime scene looked like. >> reporter: in fact, he said mullins was the first to tell police this piece of bombshell news -- gagnon had mentioned an accomplice in the killings. >> the only way you can have that information is from someone who was on the crime scene and participated in the crime. >> reporter: and then the

prosecutor tried to spin an inconvenient fact in his favor. those mystery blood drops found at the murder scene had been tested. the dna was not a match to rick but to an unidentified male. that said the prosecutor actually supported what mullins said, that rick had an accomplice. humphries believed the evidence was enough to put the defendant away. he only wished he could make the same case against rick's old girlfriend. what about bambi? i mean, she wasn't being tried in this courtroom. >> no. i think it's a travesty. >> reporter: her fingerprints are on this? >> all over it. figuratively. >> reporter: and that's just how he laid it out in his closing. he told the jury this was a story about a spoiled woman, bambi bennett, who'd manipulated her boyfriend rick gagnon into doing her murderous dirty work. get back the deed, get her mother off her back. >> he had heard from bambi how, you know, her parents were not fair to her, that they have her land. my parents are horrible people, d

>> reporter: to make things right, argued the prosecutor, the dutiful boyfriend and his right-hand man entered the house and hunted down bambi's parents in their nightclothes. the jury had just heard a drama of southern gothic proportions, dripping with family greed and hatred. now it was time for an entirely different story. >> none of the puzzle pieces fit. >> reporter: rick's defense team, including attorney barbara pratt, told the court that the state's case was heavy on fiction, light on facts. they had a puzzle. they had neat little pieces, but the pieces weren't exactly right. >> reporter: the state was so desperate to prove its case, she said, it clung to the word of a jailhouse snitch and career criminal. >> a fellow that is there to cut himself a deal and get himself some assistance, i guess, in his own case is not likely to be credible. >> reporter: not only was the snitch not to be believed, the defense told the jurors, but the state was also trying to confuse them about the mystery blood found at the crime scene. the bottom line, said pratt, the

dna from that blood cleared their client of the murders. >> the dna didn't match, and we knew the dna was not going to match rick. >> reporter: and they knew that, she said, because rick had an alibi for the night of the murders. he'd been asleep in myrtle beach with bambi. the way pratt saw it, the most challenging part of the case was the blood on rick's shoe. to explain how it got there, rick took the stand. he pointed out that on the morning the bodies were discovered police had examined him thoroughly and found nothing. >> if there was blood on my shoes that morning, i'd have been arrested right then and there. there was no blood on my shoes that morning. >> reporter: that came later, he said, when he stepped into the blood soaked bathroom. despite that police photo, he insisted the window blinds were open. and he'd worried simply that bambi might see the horror inside. >> i went in and shut the blind. i didn't think she needed to see that. >> reporter: he testified the blood got on his shoe at that moment, not before. did you go into the house and kill b

the intigation of bambi? >> absolutely not. >> reporter: were you two in a conspiracy to kill those people? >> no, sir. >> reporter: so who did kill the couple? we don't know, said the defense, but it wasn't rick gagnon. with that, the jurors filed out to deliberate. rick waited with his attorneys. and the woman many felt to be at the heart of it all held her breath. coming up -- the jury renders its verdict. >> i didn't know what to think. i didn't know what to think anymore. >> but this isn't the end of the case because finally investigators learn who left those mystery blood drops at the crime scene. >> you said they identified the killer.

jurors in rick gagnon's murder case deliberated for only a few hours. when they filed back into the courtroom, he read their faces and knew. they'd found him guilty. >> two counts of mur

received two life sentences. >> reporter: that's called a pine box sentence. >> pretty much. >> reporter: you're going to get out of the system in a pine box when you're dead. >> yeah. >> reporter: bambi bennett said she didn't want to be in court for the verdict. her attorney, jim irvin, called her with the news. >> here i am thinking, oh, my gosh, could he have done this? and then i'm going in the back of my head, there's no way he could have did this. >> reporter: rick felt as though he'd been sandbagged. >> i believed that if god saw fit to have me go home, i would go home. >> reporter: and that, thought rick, was about all he had left. faith in god and a good appellate lawyer. in this case, bob dudek. >> in my 22 or 23 years of being an appellate defense attorney, rick gagnon was only one of about two or possibly three people that i genuinely believed was innocent.

>> reporter: that certainty would mean exactly nothing to an appeals judge, unless bob and rick could come up with new evidence. then in 2009, a year after his verdict, rick had an encounter in prison with yet another inmate. >> and was all, like, excited about something. >> reporter: authorities in tennessee, the prisoner told rick, had just arrested someone for a home invasion there. >> he told me, he said, they identified the killer. >> reporter: that man's name was bruce hill. when tennessee authorities ran his dna through the database, they had a match to the mystery blood found at the parker crime scene. in 2011, a jury convicted hill of the murders of big charlie and diane. his motive for the crime was never firmly established. who's bruce hill? did you know that name? >> no. >> reporter: did you ever see him at the farm property on job sites? >> no, never.

needed proof that there was no connection between the two men. so he paid hill a visit. >> bruce hill's shown a picture of rick gagnon and his words were, i've never seen that cracker [ bleep ] before. bruce hill had been unambiguous and was very blunt that he did not know rick gagnon. >> reporter: all hill had to do now was admit that in open court and gagnon might go free. hill flatly refused. once again, rick was out of luck but not hope. >> it was the first piece of good news i'd had in a long time, you know? i was excited to see what god was getting ready to do. >> reporter: and there were developments? >> yes, sir. >> reporter: namely, the arrival of a new inmate. >> and i was in the chapel at the time. it was my job assignment. and he was brought into the chapel. >> reporter: one day the man opened up and stunned rick. he said he'd known a guy in jail

mullins, the very same who testified against rick. the man then said that mullins had shared a secret. he had lied about rick's involvement in the murders. >> i mean, i already knew it, but to hear somebody else say it, you know -- >> reporter: that mullins had lied? was pretty proud of what he was able to do? >> yeah. >> reporter: now this snitch-on-snitch story had the appeals judge's attention. >> the judge had to make a determination that the result of the trial would probably have been different. >> reporter: because mullins' story was that important in getting the conviction? >> right. >> reporter: the judge vacated rick's conviction, saying the new county solicitor, the one who had replaced humphries, could re-file charges if he wanted. the solicitor said he did not. so in 2013, after eight years inside, rick gagnon walked out of prison. he's settled on the carolina coast now, married with children. >> just the smell of the ocean, you know?

it's like freedom. it was a terrible thing that, you know, i went to prison for something i didn't do. it's changed my life. >> reporter: his old girlfriend believes her life was upended too. bambi says she's cut ties with most of the people she grew up with. the tobacco fields she still owns are pretty much her only connection to the place. >> i didn't want to be there anymore. that was my home. but my home that i had known just falsely accused me and destroyed every -- destroyed me. >> reporter: but there is something she'd like from the people of horry county, south carolina. do you want an apology? would that go anywhere for you? >> i do want an apology. no, it doesn't change what they did. and it's not going to fix what they took away. >> reporter: she'd like nothing more than an apology from you for the heartache you've caused her. >> yeah, she's not getting that. no, she's entitled to something from me,

>> reporter: what should she expect? >> i would have liked for her to have received justice in the case. >> reporter: meaning, he would have liked her charged, tried and convicted. >> and i would have liked to been an agent of that justice. >> reporter: all but forgotten amidst all the fingerpointing are bambi's sons, cody and nathan reeling from once hating their mom to now believing her completely innocent. >> i don't think she had anything to do with it. >> reporter: as a testament to that change of heart, they've joined their mom in the place she now calls home, florida. for the first time in a long while, they feel like family. >> it just took a while before you really were able to trust her with all your feelings and really tell her you loved her and hugged her and mean it, every bit of it. >> reporter: you can be her sons again? >> right. definitely. >> reporter: for that, at least, bambi is grateful. for the future, she's hopeful, even if every once in awhile she looks back in anger. >> i lost my mom and dad. my children lost their grandparents.

they're still saying the case isn't completely solved. maybe if they took their time in the beginning, we wouldn't be in this predicament today. >> reporter: maybe there are no more answers, no reason to keep digging up the past. just leave it rooted right where it is, and let the spanish moss grow. >> that's all for now. i'm lester holt. thanks for joining us. this sunday, nuclear tension. north korea claims it detonated a hydrogen bomb. what does it mean and how will the u.s. react? we'll have the latest. plus, after harvey. >> i just was in such denial. i didn't put anything up. i didn't grab anything. >> the
